IMPROVEMENT IN WINDOW-SASH SUPPORTERS.

Speciiication forming part of Letters Patent No. 124,528, dated March 12, 1872.

y on each side. C is the lower sash, and D the upper sash. E representsspiral springs, which are securely attached to the frame at the top of the boxes at their upper ends, and to guideblocks F at their lower ends. The inner portion G of the boxes is slotted, and a portion of each of the blocks H projects through Gand into the sash-grooves. This portion H en gages with the sashes by entering a recess or cavity therein, as indicated by dotted lines in Fig. 1. The outer portion J of the boxes is grooved, as seen in Fig. 2. The blocks have shoulders fi, by which they are kept in the slots and grooves as the sashes are Worked up and down. y

This arrangement is very simple and cheaply made. The springs are much more durable than cords. They work noiselessly, and nothing connected with them is liable to break or get out of order.

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- The combination, with frame A, boxes B, and sashes C D, of spiral springs E and blocks F, when said blocks F have projections H and shoulders ft', and the said boxes B are slotted at G and groovcd at J, as and for the purpose described. l
